FIELD

The present disclosure relates to the field of information technology, and in particular to a method and a device for processing a virtual model, an electronic apparatus, and a storage medium.

BACKGROUND

With the development of smart terminals, more and more applications (APPs) may be installed in the smart terminals and provide users with corresponding services.

For example, an application with a function of augmented-reality may add a virtual model to a preset image or a terminal-captured image in order to enhance interest of the image.

However, the virtual model, conventionally pre-set or pre-stored in a database, usually remains unchanged after being added to an image. Hence, representation of the virtual model is inflexible.

Advantageous of the technical solutions provided in the embodiments of the present disclosure, compared to the conventional technologies, are described below. With the method for processing a virtual model provided in the embodiments of the present disclosure, a parameter of the virtual model is adjusted based on an attribute of audio information. Since the attribute of audio information may change with time, the parameter of the virtual model may change with time after adjusting the parameter of the virtual model based on the attribute of the audio information.

FIG. 1 is a flowchart of a method for processing a virtual model according to an embodiment of the present disclosure. The method is applicable in a client to process a virtual model, and may be executed by a device for processing a virtual model. The device may be implemented in software and and/or hardware, and may be configured in an electronic apparatus such as a terminal, specifically including a mobile phone, a computer, or a tablet computer. In an alternative embodiment, the method may be applicable in a server to process a virtual model, and may be executed by a device for processing a virtual model which may be implemented in software and/or hardware, and may be configured in an electronic apparatus, such as a server. As shown in FIG. 1 , the method may specifically include steps S101 to S103.

In S101, audio information is acquired.

Reference is made to FIG. 2 . A terminal 21 may be configured to acquire the audio information. The audio information may include a sound from the terminal itself, a sound from a user, or a sound from a surrounding environment.

In an example, acquiring the audio information includes: acquiring audio information played by the terminal; and/or acquiring audio information in the surrounding environment.

For example, the terminal 21 may play the audio information and obtain the audio information played by the terminal 21. Alternatively, the terminal 21 may not play the audio information, but acquire the audio information in the surrounding environment. The terminal 21 may be provided with a sound sensor or audio sensor. The sound sensor or audio sensor may be, for example, a single microphone or a microphone array of multiple microphones.

The microphone or microphone array may collect the audio information played by the terminal 21 or the audio information in the surrounding environment of the terminal 21. The audio information in the surrounding environment of the terminal 21 may be played by other devices in the surrounding environment of the terminal 21, or may come from a user in the surrounding environment of the terminal 21.

In another application scenario, the terminal 21 may store the audio information in advance. Alternatively, the terminal 21 may acquire the audio information from another device, such as another terminal or server.

In addition, the terminal 21 may be provided with a display component. The display component may be a screen. The terminal 21 may display a target image on the screen. The target image may specifically include, for example, an image of a human face or another target object. Specific content and form of the target image are not limited herein.

In an implementation, the terminal 21 may be installed with a camera. In a case that the camera is turned on by the user, the camera may be configured to capture a target image, such as an image of a human face. Alternatively, the terminal 21 may be installed with an image application or video application. In a case that the camera is activated by the application, the camera captures a target image, such as an image of a human face. Further, the terminal 21 displays the target image on the screen.

In another implementation, the terminal 21 stores a preset image locally. In an example, the terminal 21 may acquire the preset image from another terminal or server. The preset image may be an image including a target object (such as a human face or another target object). Further, the terminal 21 processes the preset image through a preset image processing method, in order to extract an image of the target object from the preset image. The image of the target object may be determined as the target image. Further, the target image is displayed on the screen by the terminal 21.

It may be understood that, the above-mentioned methods for the terminal 21 to acquire the target image and display the target image on the screen are merely illustrative and not intended to be limiting. Other methods may also be possible in other embodiments.

In an example, the terminal 21 may further display a virtual model in the target image. In an embodiment, illustrative description is made taking an image of a human face as an example. It should be understood by those skilled in the art that, the target image in other embodiments is not limited to image of human face, and may be an image of another object. The target object is not limited to a human face, but may be any other object, which is not limited herein. The virtual model may specifically be a three-dimensional (3D) object in a virtual three-dimensional space rendered by a computer through a graphics technology. For example, in a case that a user uses a terminal to capture a video or image of a scene, the terminal may analyze image information of the video or image, obtain three-dimensional information of the scene, and add a virtual model to the video or image and perform rendering and synthesis through the computer graphics technology. A material of the virtual model may specifically include: color, texture, transparency, light and shadow effects, and the like. The material of the virtual model may be specifically defined or characterized by a series of graphics algorithms and rules. The material of the virtual model is specifically used to define the color, texture, transparency, light and shadow effect, and the like, of the virtual model for visual presentation.

In an implementation, the terminal 21 may acquire a sliding trajectory inputted by the user on the screen, generate a virtual model corresponding to the sliding trajectory, and display the virtual model at a first position in the target image (for example, an image of a human face or another target object).

In another implementation, the terminal 21 may perform detection on the image of the target object, for example, detect feature information of the image of the target object, generate a virtual model according to the feature information, and display the virtual model at a first position in the image of the target object. The first position may be determined by the user, or may be predefined by the terminal 21, or may be a random position in the image.

In an embodiment of the present disclosure, a quantity of virtual models displayed in the image of the target object may be one or more. In addition, the virtual model may be a three-dimensional model or a two-dimensional model.

In an example, the terminal 21 may acquire the audio information before displaying the virtual model in the image of the target object, or after displaying the virtual model in the image of the target object.

In S102, a parameter of the virtual model is adjusted based on an attribute of the audio information.

For example, after acquiring the audio information, the terminal 21 may analyze and extract an attribute of the audio information by using a digital signal processing technology, a deep learning technology, or other technologies. Further, the terminal 21 may adjust a parameter of the virtual model based on the attribute of the audio information. Since the attribute of the audio information usually changes with time, the parameter of the virtual model after the adjustment changes with time.

In an example, the attribute of the audio information includes at least one of: tone, volume, accent, or spectral intensity.

In an example, the parameter of the virtual model includes at least one of: a shape, a dimension, and a first color of the virtual model; or a position, a width, a moving speed, and a second color of a preset area on the virtual model.

An embodiment is described taking an example in which the target image is an image of a human face. In another embodiment, the target image is not limited to the image of a human face, and may be, for example, an image of another target object. That is to say, the target object in the target image is not limited to a human face, but may be another object.

Reference is made to FIG. 3 . An image of a human face is displayed on the screen of the terminal 21. Further, the user may input a sliding trajectory on the screen. The terminal 21 may acquire target points related to the sliding trajectory. The target points may be multiple trajectory points or sampling points on the sliding trajectory. Alternatively, the target points may be multiple sampling points on a fitted curve obtained by the terminal 21 fitting multiple trajectory points on the sliding trajectory. Further, the terminal 21 may acquire a preset sub-model corresponding to each of the multiple target points. Different target points may correspond to a same or different preset sub-models. In addition, a specific shape of the preset sub-model corresponding to each of the target points is not limited here. For example, the preset sub-model may be a cylinder in an embodiment. The terminal 21 converts the preset sub-model corresponding to each of the target points into a target sub-model based on geometric information of the target point. The target sub-model may be obtained by apply a degree of curvature and/or scaling on of the preset sub-model. Further, the terminal 21 joins the target sub-models corresponding to the target points to form a virtual model. The virtual model may appear similar to a horn, as shown in FIG. 3 .

In an example, the terminal 21 may display the virtual model similar to a horn at a first position in the image of the human face. The first position may be a preset position or a random position. A specific form of the virtual model is not limited here, and other forms of the virtual model are possible in other embodiments, for example. In FIG. 3 , numeral 22 indicates the first position (μ, ν), where (μ, ν) may represents coordinates of the first position in a coordinate system for the human face; and numeral 23 indicates the virtual model attached to the first position (μ, ν). In an example, the terminal 21 may overlap a center of a bottom surface of the virtual model 23 to the first position 22 on the human face. A point at the first position 22 may specifically be a key point on the human face. In addition, an orientation of the key point in the three-dimensional space is consistent with a Y-axis of a model coordinate system where the virtual model 23 is located. A direction of the Y-axis of the model coordinate system may pass through the center of the bottom surface of the virtual model 23 and be perpendicular to the bottom surface.

In an embodiment, after attaching the virtual model 23 to the first position 22 of the human face, the terminal 21 may further determine a second position 24 on the human face that is symmetrical to the first position 22. The second position may be specifically represented as (1−μ, ν), where (μ, ν) and (1−μ, ν) both indicate coordinates in the coordinate system for the human face. Further, the virtual model 23 may be referred to as a first virtual model. The terminal 21 may display, at the second position (1−μ, ν), a second virtual model that is a mirror of the virtual model 23. The second virtual model may be the virtual model 25 shown in FIG. 3 .

In an embodiment of the present disclosure, the virtual model 23 and/or the virtual model 25 may include at least one preset area. The preset area may specifically be a light-emitting area, which may be referred to as a light band. Reference is made to FIG. 4 , in which numerals 41 to 45 represent preset areas on the virtual model 23, and numerals 51 to 55 represent preset areas on the virtual model 25. Different preset areas may present different colors. Alternatively, different preset areas may present a same color. In a case that the virtual model 23 and the virtual model 25 are mirror images of each other, preset areas symmetrical to each other on respective virtual models 23 and 25 may preset a same color or different colors. For example, a preset area 41 and a preset area 51 are symmetrical to each other, and may present a same color or different colors. Schematic illustration here is made taking an example in which the preset areas symmetrical to each other present a same color.

In an embodiment of the present disclosure, the parameter of the virtual model may specifically include a parameter of the virtual model itself and/or a parameter of a preset area on the virtual model. For example, the parameter of the virtual model itself may include a shape, a dimension, a color, and the like of the virtual model, where the color of the virtual model itself is referred to as a first color. Specifically, the color of the virtual model itself may refer to a color of the virtual model before rendering the preset area on the virtual model. In addition, the color of the virtual model itself may be referred to as a base color. In order to be distinguishing from the base color, a color of each preset area on the virtual model may be referred to as a second color. The second color may be superimposed on the base color. That is, a color presented by the preset area on the screen may be a color obtained after the second color of the preset area is superimposed on the base color.

In an example, the parameter of the preset area on the virtual model may include: a position, a width, a moving speed, a second color, and the like, of the preset area. The position of the preset area may specifically refer to a position at which the preset area is located on the virtual model. The position at which the preset area is located on the virtual model may be indicated by a vertex color corresponding to the preset area. In an embodiment, the vertex color may be indicated by values of points at specific positions on an upper surface and lower surface of the preset area.

A specific form of the virtual model is not limited in the embodiments. In the following, a virtual model (such as a cone) simpler than the virtual model shown in FIG. 3 or FIG. 4 is used to provide an illustration of the parameter of the preset area and facilitate understanding of the parameter. Reference is made to FIG. 5 , which shows a cone as a virtual model in another form. A center of a lower surface of the virtual model is A1, and a top vertex of the virtual model is A2. A position of A1 may be marked with a value of 0, and a position of A2 may be marked with a value of 1. The shadowed area in FIG. 5 may be any preset area on the virtual model in the form of a cone. A center of an upper surface of the preset area is A3, and a center of a lower surface of the preset area is A4. A3 and A4 are on the line connecting A1 and A2. In addition, there are other points on the line connecting A3 and A4, and values corresponding to the points on the line continuously increase along a direction from A1 to A2. The value corresponding to a point on the line is related to a distance from the point to A1. For example, a point farther from A1 corresponds to a larger value. In addition, the value corresponding to any point on the line is in a range of [0, 1]. For example, in a case that A4 corresponds to a value of 0.2 and A3 corresponds to a value of 0.4, then the vertex color corresponding to the preset area shown in FIG. 5 is denoted as L2, where L2 is in a range of [0.2, 0.4]. The vertex color of the virtual model is denoted as L1, and L1 is in a range of [0, 1].

In an alternative embodiment, the vertex color of the virtual model shown in FIG. 5 may depend on A1′ and A2′ shown in FIG. 6 , and the vertex color of the preset area may depend on A3′ and A4′ shown in FIG. 6 . Specifically, A1′ corresponds to a value of 0, and A2′ corresponds to a value of 1. A value corresponding to A3′ is related to a distance from A3′ to A1′, and a value corresponding to A4′ is related to a distance from A4′ to A1′. For example, in a case that A4′ corresponds to a value of 0.2 and A3′ corresponds to a value of 0.4, then the vertex color corresponding to the preset area is denoted as L2′, where L2′ is in a range of [0.2, 0.4]. The vertex color of the virtual model is denoted as L1′, and L1′ is in a range of [0, 1].

In addition, on the basis of FIG. 5 or FIG. 6 , a width of the preset area may be defined as a distance between points representing vertex colors in the preset area. For example, the width of the preset area is equal to a distance between A3 and A4 as shown in FIG. 5 , or a distance between A3′ and A4′ as shown in FIG. 6 .

In addition, on the basis of FIG. 5 or FIG. 6 , the preset area may move on the virtual model, or may remain stationary on the virtual model. A position of the preset area before moving on the virtual model is an initial position of the preset area on the virtual model. When the preset area moves on the virtual model, a moving speed of the preset area is not equal to 0, and the preset area is at different positions at different times. When the preset area remains stationary on the virtual model, the moving speed of the preset area is 0, and the preset area is at a same position at different times.

Therefore, a calculation of the vertex color corresponding to each preset area shown in FIG. 4 is similar to a calculation of the vertex color corresponding to the preset area shown in FIG. 5 or FIG. 6 , and is not repeated here. The width of each preset area as shown in FIG. 4 may be calculated in a similar manner as shown in FIG. 5 or FIG. 6 . In addition, moving speeds of preset areas shown in FIG. 4 may be the same or different. Second colors of preset areas as shown in FIG. 4 may be the same or different.

In an embodiment of the present disclosure, the terminal 21 may adjust the parameter of the virtual model 23 and/or the virtual model 25 shown in FIG. 4 based on tone, volume, accent, spectral intensity, and other attributes, of the audio information.

Hereinafter, an illustrative description is made by taking an example in which the terminal 21 adjusts the parameter of the virtual model 23 shown in FIG. 4 based on the tone, the volume, the accent, the spectral intensity, and other attributes, of the audio information. The parameter of the virtual model 23 includes: the first color of the virtual model 23 (that is, the base color), and the position, the width, the moving speed, the second color, and the like, of each preset area on the virtual model 23. It may be understood that the attribute of the audio information may change over time, for example, in real time. Therefore, by adjusting the parameter of the virtual model 23 based on the attribute of the audio information, a change of the parameter of the virtual model 23 with the change of the attribute of the audio information may be realized, and thus a real-time change of the virtual model 23 is realized.

The audio information has multiple attributes, and the virtual model 23 has multiple parameters. A correspondence between the attributes of the audio information and the parameters of the virtual model 23 is not limited when adjusting the parameters of the virtual model 23 based on the attributes of the audio. For example, one parameter of the virtual model 23 may be adjusted based on a single attribute of the audio information or multiple attributes of the audio information.

In S103, the virtual model is displayed in the target image based on the parameter of the virtual model after the adjustment.

In an implementation, in a case that a virtual model 23 is previously displayed in the image of a human face, the terminal 21 may, after adjusting the parameter of the virtual model 23 based on an attribute of the audio information, update the virtual model 23 in the image (that is, display the virtual model after the adjustment) based on the adjusted parameter. Since the parameter of the virtual model 23 after the adjustment changes with time, the virtual model 23 displayed in the target image (such as the image of the human face) changes with time.

In another implementation, in a case that the virtual model 23 is not previously displayed in the image of the human face, the terminal 21 may, after adjusting the parameter of the virtual model 23 based on an attribute of the audio information, generate the virtual model 23 based on the parameter of the virtual model 23 after the adjustment, and display the virtual model 23 in the image of the human face.

It may be understood that, in a case that the parameter of the virtual model 23 changes in real time with the attribute of the audio information, the virtual model 23 on the image of the human face may also change in real time. For example, a base color of the virtual model 23 may be changed in real time, and a position, a width, a moving speed, a second color, and the like, of each preset area on the virtual model 23 may also be changed in real time. In addition, a quantity of preset areas to be displayed on a single virtual model is not limited in the embodiments of the present disclosure. For example, the quantity of preset areas may be determined by a user or based on a dimension or shape of the virtual model, or may be preset.

With the method for processing a virtual model provided in the embodiments of the present disclosure, a parameter of the virtual model is adjusted based on an attribute of audio information. Since the attribute of audio information may change with time, the parameter of the virtual model may change with time after adjusting the parameter of the virtual model based on the attribute of the audio information. Further, in response to the parameter of the virtual model changing with time, the virtual model displayed in the target image changes accordingly. That is to say, the virtual model displayed in the target image may change with the change of the audio information, and change of the audio information may be visually reflected through the virtual model. Hence, a linkage between a visual presentation and an audio presentation is achieved, and flexibility in presenting the virtual model is improved.

On the basis of the above embodiments, several implementations of adjusting the parameter of the virtual model based on the attribute of the audio information are described below.

In an implementation, adjusting the parameter of the virtual model based on the attribute of the audio information includes: adjusting the speed at which the preset area moves on the virtual model based on the tone of the audio information.

For example, the tone of the audio information may be denoted as tone, and the speed at which the preset area moves on the virtual model may be denoted as speed. In an example, the terminal 21 may adjust the speed at which the preset area moves on the virtual model based on the tone of the audio information. A relationship between the tone and the speed may be expressed as formula (1):

$\begin{matrix} {{speed} = {{mix}\left( {2.,10.,{{clamp}\left( {\frac{tone}{255.},0.,1.} \right)}} \right)}} & (1) \end{matrix}$

In formula (1), 2.0 represents a minimum value of the speed, 10.0 represents a maximum value of the speed, 255.0 represents a maximum estimated value of the tone; and therefore

$\frac{tone}{255.}$

ranges from 0 to 1. In addition, 0.0 and 1.0 are used to further guarantee that

$\frac{tone}{255.}$

ranges from 0 to 1. The item clamp represents a function that has 3 input parameters, i.e., x, 0.0, and 1.0 in the listed-order. The clamp (x, 0.0, 1.0) defines that: 0 is outputted in response to x being less than 0; 1 is outputted in response to x being greater than 1; and x is outputted in response to 0≤x≤1, where x may correspond to different expressions in different scenarios. In this embodiment, x corresponds to tone

$\frac{tone}{255.}.$

It may be understood that some real numbers, such as 2.0, 10.0, 255.0, 0.0, 1.0, and the like, described for formula (1) may be illustrative in an embodiment. These real numbers may be schematically adjusted in different application scenarios, and are not limited herein.

In another implementation, adjusting the parameter of the virtual model based on the attribute of the audio information includes: adjusting the first color of the virtual model based on the tone, the volume, and the accent of the audio information.

For example, the tone of the audio information may be denoted as tone, the volume of the audio information may be denoted as volume, and the accent of the audio information may be denoted as onset. In an example, the terminal 21 may adjust the first color, i.e., the base color (denoted as albedoColor), of the virtual model based on the tone (denoted as tone) of the audio information, the volume (denoted as volume) of the audio information, and the accent (denoted as onset) of the audio information. A relationship of tone, volume, onset, and albedoColor may be expressed as formula (2):

$\begin{matrix} {{albedoColor} = {{float}4\left( {\frac{tone}{255.},\frac{volume}{25{5.0}},\frac{onset}{255.},1.} \right)}} & (2) \end{matrix}$

In formula (2), float4 indicates that a 4-dimensional vector RGBA (red, green, blue, and transparency) is formed by

$\frac{tone}{255.},\frac{volume}{25{5.0}},\frac{onset}{255.},1.$

The 255.0 in

$\frac{tone}{255.}$

represents a maximum estimated value of tone, the 255.0 in volume/255.0 represents a maximum estimated value of volume, the 255.0 in

$\frac{onset}{255.}$

represents a maximum estimated value of onset, and the 1.0 represents a transparency. Each of the

$\frac{tone}{255.},\frac{volume}{255.}$

and the

$\frac{onset}{255.}$

ranges from 0 to 1.

It may be understood that some real numbers in formula (2), for example, 255.0, 1.0, and the like, may be illustrative in this embodiment. These real numbers may be adjusted in different application scenarios, and are not limited here.

In yet another implementation, adjusting the parameter of the virtual model based on the attribute of the audio information includes: adjusting the second color of the preset area on the virtual model based on the spectral intensity of the audio information.

For example, the second color of a preset area may be denoted as BandColor. The BandColor may be determined based on an initial color and a spectral intensity of the audio information. For example, the initial color is denoted as ArtistColor, and the spectral intensity of the audio information is denoted as SpectrumIntensity. In an example, the spectrum intensity of the audio information may be obtained after analyzing a spectrum of the audio information. The spectral intensity of the audio information may be an array, for example, SpectrumIntensity[i] represents the intensity of an i-th spectrum. Since a virtual model may include multiple preset areas, the second colors of the multiple preset areas may be distinguished from each other. For example, the second color of the i-th preset area is denoted as BandColor[i]. The BandColor[i] may be determined by formula (3):

BandColor[i]=ArtistColor[i]*SpectrumIntensity[i]  (3)

In formula (3). ArtistColor[i] represents an initial color of the i-th preset area. In an embodiment, SpectrumIntensity[i] may further represent the spectral intensity corresponding to the i-th preset area. For example, the spectral intensity corresponding to the i-th preset area may vary with time, and therefore the second color of the i-th preset area may change continuously. In addition, the initial color of the i-th preset area may be preset. A process of adjusting the second color of the i-th preset area based on the spectral intensity of the audio information may specifically implemented by adjusting a brightness of the second color, so that the brightness of the second color can change with the change of the spectral intensity. For example, the initial color of the i-th preset area is red. The second color of the i-th preset area may be bright red in a case that the spectral intensity of the audio information is relatively large. The second color of the i-th preset area may be dark red in a case that the spectral intensity of the audio information is relatively small. Different preset areas may have a same initial color or different initial colors.

In a further implementation, adjusting the parameter of the virtual model based on the attribute of the audio information includes: adjusting a width of the preset area on the virtual model based on an accent of the audio information.

For example, the width of the preset area is denoted as lineWidth. Adjustment of the width of the preset area based on the accent (onset) of the audio information may be implemented based on formula (4):

$\begin{matrix} {{lineWidth} = {0.03 \star {\min{\left( {5.,{\max\left( {1.,\frac{onset}{60.}} \right)}} \right).}}}} & (4) \end{matrix}$

In formula (4), 0.03 represents an initial width of the preset area, 60.0 represents a scaling value for scaling the input accent, and 5.0 and 1.0 are set for a minimum value function min and a maximum value function max, in order to control the

$\frac{onset}{60.}$

in a range from 1.0 to 5.0.

It can be understood that some real numbers described in formula (4), for example, 0.03, 5.0, 60.0, 1.0, and the like, may be illustrative in this embodiment. These real numbers may be adjusted in different application scenarios, and are not limited here. Specifically, the real numbers in the above formulas (1), (2) and (4) may be empirical parameters, and may be determined, for example, based on a value range of the attribute of the audio information.

In yet another implementation, adjusting the parameter of the virtual model based on the attribute of the audio information includes: adjusting a speed at which the preset area moves on the virtual model based on the tone of the audio information; and adjusting a position of the preset area based on the speed at which the preset area moves on the virtual model and an initial position of the preset area on the virtual model.

For example, the initial position of the preset area on the virtual model may be denoted as linePos, and the speed at which the preset area moves on the virtual model may be denoted as speed. In response to the speed being not 0, the position of the preset area on the virtual model may change in real time. For example, a current position of the preset area on the virtual model is denoted as linePos′ and there has linePos′=linePos+time*speed, where time represents a time interval. Change of the speed with the audio information is as described above, and is not repeated here.

In the above embodiments of the present disclosure, the speed at which the preset area moves on the virtual model is adjusted based on the tone of the audio information: the first color of the virtual model is adjusted based on the tone, the volume and the accent of the audio information: the second color of the preset area is adjusted based on the spectral intensity of the audio information; the width of the preset area on the virtual model is adjusted based on the accent of the audio information; a position of the preset area is adjusted based on the speed at which the preset area moves on the virtual model and the initial position of the preset area on the virtual model. Hence, the parameters of the preset area can change with the attributes of the audio information. The attributes of the audio information are presented in a visual form of 3D rendering. Thereby, a visual performance of the virtual model may change with the audio information, so as to improve a flexibility of a representation of the virtual model.

FIG. 7 is a flowchart of a method for processing a virtual model according to another embodiment of the present disclosure. On the basis of the above embodiments, the method for processing a virtual model is further described in details in this embodiment. As shown in FIG. 7 , the method in this embodiment is applicable to a terminal, and specifically includes steps S701 to S705.

In step S701, a virtual model is displayed in a target image.

As mentioned with reference to FIG. 3 , the terminal 21 may display the virtual model 23 and the virtual model 25 in the target image. The target image includes, for example, an image of a human face or other target objects.

In S702, a preset area is displayed on the virtual model based on an initial parameter of the preset area.

In this embodiment, the preset area on the virtual model may have an initial parameter. The initial parameter of the preset area may include: an initial position, an initial width, an initial moving speed, and an initial color of the preset area. The initial position of the preset area may specifically refer to an initial position of the preset area on the virtual model. The initial moving speed of the preset area may specifically refer to an initial speed at which the preset area moves on the virtual model. In an example, the initial parameter of the preset area may be pre-configured by the terminal 21. Alternatively, the initial parameter of the preset area may be set by a user. For example, an icon or button for parameter configuration may be displayed on a user interface of the terminal 21, and the terminal 21 may determine the initial parameter of the preset area in response to a user operation on the icon or button. In an example, the user may not only configure a quantity of preset areas, but also set the initial parameter of the preset area. Further, the terminal 21 may display the preset area on the virtual model based on the initial parameter of the preset area. As shown in FIG. 4 , on the basis of FIG. 3 , the terminal 21 may display the preset area on the virtual model based on the initial parameter of the preset area. In an example, a process of displaying the preset area on the virtual model by the terminal 21 may specifically be rendering of the preset area, such as a light band.

In S703, audio information is acquired.

An implementation and specific principle of S703 is the same as the S101, and is not repeated here.

In S704, a parameter of the virtual model is adjusted based on an attribute of the audio information.

For example, the terminal 21 adjusts the parameter of the virtual model 23 and/or the virtual model 25 as shown in FIG. 4 , based on the attribute of the audio information. The parameter of the virtual model 23 includes a base color of the virtual model 23, and a position, width, moving speed, second color, and the like, of a preset area on the virtual model 23. The parameter of the virtual model 25 includes a base color of the virtual model 25, and a position, width, moving speed, second color, and the like, of a preset area on the virtual model 25. Thereby, the parameter of the virtual model 23 and/or the virtual model 25 can be changed with change of the audio information.

An implementation and specific principle of S704 may refer to the implementations described in the foregoing embodiments, which is not repeated here.

In S705, the virtual model is displayed in a target image based on the parameter of the virtual model after the adjustment.

In an example, displaying the virtual model in the target image based on the parameter of the virtual model after the adjustment includes: updating the virtual model in the target image based on the parameter of the virtual model after the adjustment.

For example, on the basis of FIG. 4 , when the parameter of the virtual model 23 and/or the virtual model 25 are changed, the terminal 21 may update the virtual model 23 and/or the virtual model 25 in the image of the human face based on the parameter of the virtual model 23 and/or the virtual model 25 after updating.

Thereby, the base color of the virtual model 23 and/or the virtual model 25 displayed in the image, and the position, width, moving speed, color, and the like, of the preset area on the virtual model 23 and/or the virtual model 25 can change with the audio information.

Alternatively, the method further includes: smoothing a brightness of the preset area based on the initial parameter of the preset area.

In an implementation, after S702, the brightness of the preset area is smoothed based on the initial parameter of the preset area. For example, as shown in FIG. 4 , after displaying the preset area on the virtual model 23 and/or the virtual model 25 based on the initial parameter of the preset area, the terminal 21 may further smooth the brightness of the preset area based on the initial parameter of the preset area.

In another implementation, S702 may specifically include: smoothing a brightness of the preset area based on an initial parameter of the preset area; and displaying the preset area on the virtual model. For example, as shown in FIG. 3 , after displaying the virtual model 23 and the virtual model 25 in the image of the human face, the terminal 21 may perform a smoothing process on the brightness of the preset area based on the initial parameter of the preset area, and then display the preset area on the virtual model 23 and the virtual model 25 based on the initial parameter of the preset area and smoothed brightness of the preset area.

The following description is made taking the virtual model 23 as an example, in order to introduce a process of smoothing the brightness of the preset area on the virtual model 23. For example, multiple preset areas may be displayed on the virtual model 23. An initial position of a preset area on the virtual model 23 is denoted as linePos, an initial width of the preset area is denoted as lineWidth0, and an initial color of the preset region is denoted as BandColor0, where BandColor0 may be the same as the ArtistColor described above. The initial moving speed of the preset area on the virtual model 23 is denoted as speed0. Further, the terminal 21 performs a smoothing processing on the brightness of the preset area based on the initial parameter of the preset area, such as the linePos, lineWidth0, BandColor0, and speed0. The linePos, lineWidth0, BandColor0, and speed0 may have fixed values. Reference is made to FIG. 8 . The dotted line represents a center line of the preset area, and the smoothing process on the brightness of the preset area may implemented by smoothing the brightness from the center line in the preset area to an edge of the preset area.

In an example, smoothing the brightness of the preset area based on the initial parameter of the preset area includes: performing a first smoothing process on the brightness of the preset area based on an initial width of the preset area and an initial position of the preset area; and performing a second smoothing process on the brightness of the preset area based on a result after the first smoothing process and a preset smoothing parameter.

For example, the terminal 21 may perform the first smoothing process on the brightness of the preset area based on the initial width lineWidth0 of the preset area and the initial position linePos of the preset area on the virtual model 23. A result after the first smoothing process is denoted as OutputBand1. The OutputBand1 is calculated through formula (5):

$\begin{matrix} {{{OutputBand}1} = {{{smoothstep}\left( {{{linePos} - \frac{lineWidth}{2}},{linePos},x} \right)} - \text{ }{{{smoothstep}\left( {{linePos},{{linePos} + \frac{lineWidth}{2}},x} \right)}.}}} & (5) \end{matrix}$

In formula (5), there has lineWidth=lineWidth0; and x represents geometric information of the virtual model, such as texture coordinates, vertex colors, and the like. In an embodiment, x may specifically represent the vertex color of the virtual model 23, for example, [0, 1]. The smoothstep represents a function for smoothing the brightness of the preset area. The smoothstep may be a general calculation function with 3 input parameters, in which a first input parameter is denoted as a, a second input parameter is denoted as b, and a third input parameter is denoted as t, for example. The variables a, b, and t may be understood as input parameters for the smoothstep function without loss of generality. In different scenarios, each of a, b, t may represent different meanings or expressed as different expressions. The smoothstep may be expressed by formula (6):

$\begin{matrix} {{{{smoothstep}\left( {a,b,t} \right)} = {{3m^{2}} - {2m^{3}}}},{m = {{\max\left( {0,{\min\left( {1,\frac{t - b}{b - a}} \right)}} \right)}.}}} & (6) \end{matrix}$

For

${smoothstep}\left( {{{linePos} - \frac{lineWidth}{2}},{linePos},x} \right)$

in formula (5),

${linePos} - \frac{lineWidth}{2}$

corresponds to a, linePos corresponds to b, and x corresponds to t.

For

${smoothstep}\left( {{{linePos} - \frac{lineWidth}{2}},{linePos},x} \right)$

in formula (5), linePos corresponds to a,

${linePos} + \frac{lineWidth}{2}$

corresponds to b, and x corresponds to 1.

For example, the initial position of the preset area on the virtual model shown in FIG. 8 may be a centerline position of the preset area. In addition, a bottom position of the virtual model shown in FIG. 8 may be represented by 0, a top position of the virtual model may be represented by 1, and the centerline position may be represented by 0.5. The initial width of the preset area is, for example, 0.2, then a position of an upper edge of the preset area can be represented by 0.6, and a position of a lower edge of the preset area may be represented by 0.4.

The result OutputBand1 of the first smoothing process may be represented as a curve as shown in FIG. 9 . Specifically, a horizontal axis of the coordinate system shown in FIG. 9 represents the vertex color of the virtual model, ranging from 0 to 1, in which a range of 0.4 to 0.6 is the vertex color corresponding to the preset area shown in FIG. 8 . A vertical axis of the coordinate system represents brightness. The curve shown in FIG. 9 indicates changes of the brightness from the centerline position 0.5 of the preset area to the upper edge position 0.6 and the lower edge position 0.4 of the preset area. For example, the brightness of the preset area is greatest at the centerline position 0.5, and gradually decreases from the centerline position 0.5 to the upper edge position 0.6 or the lower edge position 0.4.

Further, on the basis of the first smoothing result OutputBand1, a second smoothing process may be performed on the brightness of the preset area based on a preset smoothing parameter y and the initial color BandColor0 of the preset area. Specifically, the second smoothing process may smooth a color brightness of the preset area. That is, after the second smoothing process, the color brightness of different positions in the preset area is a result of the second smoothing process. The result of the second smoothing process is denoted as OutputBand2. The OutputBand2 is calculated through formula (7):

OutputBand2=pow(OutputBand1,y)·BandColor  (7)

In formula (7), there has BandColor=BandColor0. The preset smoothing parameter y is used to control an edge brightness smoothing effect of the preset area. The pow(OutputBand1,y) represents a result of smoothing the brightness of the preset area again using the preset smoothing parameter y based on the first smoothing result OutputBand1, where pow represents a smoothing function. The pow(OutputBand1,y) is multiplied with the initial color BandColor0 so as to realize a distribution of the brightness of the initial color BandColor0 in accordance with pow(OutputBand1,y) in the preset area.

In a case that y is greater than 1, the result pow(OutputBand1,y) after smoothing the brightness of the preset area again may be expressed as a curve as shown in FIG. 10 . Compared with the OutputBand1 after the first smoothing process, the brightness shown in FIG. 10 changes slower and smoother from the centerline position 0.5 to the upper edge position 0.6 or the lower edge position 0.4, especially in regions close to the upper edge position 0.6 or the lower edge position 0.4.

In a case that y is equal to 1, the result pow(OutputBand1,y) after smoothing the brightness of the preset area again may be expressed as a curve as shown in FIG. 11 . In such case, a smoothing effect of pow(OutputBand1,y) is substantially the same as a smoothing effect of the first smoothing result OutputBand1.

In a case that y is less than 1, the result pow(OutputBand1,y) after smoothing the brightness of the preset area again may be expressed as a curve as shown in FIG. 12 . Compared with the OutputBand1 after the first smoothing process, the brightness shown in FIG. 12 changes faster from the centerline position 0.5 to the upper edge position 0.6 or the lower edge position 0.4, especially in regions close to the upper edge position 0.6 or the lower edge position 0.4. In this case, edges of the preset area are sharper.

Based on FIG. 10 to FIG. 12 , y may affect a transition speed of the brightness. For example, the transition of brightness is slow in a case that y is greater than 1, and the transition of brightness is fast in a case that y is less than 1. In addition, y may have a certain influence on the width of the preset area while affecting the transition speed of the brightness. That is, the width of the preset area actually presented may depend on both lineWidth and y. Alternatively, the width of the preset area actually presented may depend on both the initial width line Width0 and y.

Since OutputBand1 does not include information of color and OutputBand2 includes information of color, OutputBand2 can present a color effect of the preset area, such as color brightness. For example, assuming that the initial color BandColor0 of the preset area is red, after processed by formula (7), the centerline position of the preset area becomes bright red, and an upper edge position and a lower edge position of the preset area are dark red. A brightness of the red color gradually decreases from the centerline position of the preset area to the upper edge position and the lower edge position of the preset area, and conforms to the curve represented by OutputBand2.

After the smoothing process on the brightness of the preset area based on the above formula (5) and formula (7), in a case that the initial moving speed of the preset area is 0, the preset area displayed by the terminal 21 on the virtual model 23 may be stationary. That is, the preset area is displayed on the virtual model 23 in a stationary manner with the preset initial position, the initial width, the initial color, and the brightness after the smoothing processes in accordance with formula (5) and formula (7).

In another embodiment, the preset area may be non-stationary. For example, in a case that the initial moving speed of the preset area is not 0, the performing the first smoothing process on the brightness of the preset area based on the initial width of the preset area and the initial position of the preset area includes: performing the first smoothing process on the brightness of the preset area based on the initial width of the preset area, the initial position of the preset area, and an initial moving speed of the preset area.

For example, in a case that the initial moving speed of the preset area is not 0, the initial moving speed speed0 of the preset area may be introduced on the basis of formula (5). In this case, the first result OutputBand1 may be calculated through formula (8):

$\begin{matrix} {{{OutputBand}1} = {{{smoothstep}\left( {{{linePos} - \frac{lineWidth}{2}},{linePos},{input}} \right)} - {{smoothstep}{\left( {{linePos},{{linePos} + \frac{lineWidth}{2}},{input}} \right).}}}} & (8) \end{matrix}$

In formula (8), there has input=frac(x+time·speed), where input represents an input after modification, time represents a time increment, and the speed here in the input is equal to speed0. A second smoothing process may be further performed on the basis of formula (8). The result after the second smoothing process is denoted as OutputBand2, and OutputBand2 is calculated through formula (9):

OutputBand2=pow(OutputBand1,y)·BandColor  (7)

In formula (9), OutputBand1 is the same as the OutputBand1 in formula (8), and there has BandColor=BandColor0. Reference may be made to FIG. 10 to FIG. 12 as described above for a relationship between the preset smoothing parameter y and the smoothing effect of pow(OutputBand1,y). The pow(OutputBand1,y) in formula (9) indicates a result of a second smoothing process on the brightness of the preset area with the preset smoothing parameter y, on the basis of the first result OutputBand1 obtained by formula (8). The pow represents a smoothing function. After smoothing the brightness of the preset area using formula (8) and formula (9), since the initial moving speed of the preset area is not 0, the preset area displayed by the terminal 21 on the virtual model 23 moves at the initial moving speed. For example, the preset area moves from a lower portion of the virtual model 23 to an upper portion of the virtual model 23 with the initial moving speed. After reaching the top of the virtual model 23, the preset area may repeatedly move from the lower portion of the virtual model 23 to the upper portion of the virtual model 23. Such repeated movement of the preset area on the virtual model may be a default configuration, that is, the preset area moves repeatedly as configured if the preset area is movable on the virtual model. In addition, the repetition of movement of the preset area on the virtual model may be configured at the same time when the user configures the initial parameter of the preset area. During the movement of the preset area, a width of the preset area remains the initial width, a color of the preset area remains the initial color, and a brightness of the preset area is smoothed by using formula (8) and formula (9).

It can be understood that, with the above method, multiple preset areas can be displayed on the virtual model 23. Each of the preset areas has its own initial position, initial width, initial moving speed, initial color, and other initial parameters.

In the method for processing a virtual model provided by the embodiments of the present disclosure, the brightness of the preset area is smoothed by using the initial parameter of the preset area. Hence, a smooth change of the brightness of the preset area from the centerline position to the upper edge position of the preset area and to the lower edge position of the preset area is realized, so that a visual effect of the preset area is enhanced.

FIG. 13 is a flowchart of a method for processing a virtual model according to an embodiment of the present disclosure. The method is further illustrated hereinafter on the basis of the above-mentioned embodiments. Reference is made to FIG. 13 . The method is applicable to a terminal, and specifically includes S1301 to S1304.

In S1301, audio information is acquired.

Implementations and specific principles of S1301 are the same as those for S101, and are not repeated here. It can be understood that, in an embodiment, S701 and S702 as shown in FIG. 7 may be executed before S1301.

In S1302, a parameter of the virtual model is adjusted based on the attribute of the audio information.

Implementations and specific principles of S1302 may refer to what described in the foregoing embodiments, which are not repeated here.

In S1303, the virtual model is displayed in a target image based on the parameter of the virtual model after the adjustment.

Implementations and specific principles of S1303 may refer to what described in the foregoing embodiments, which are not repeated here.

In S1304, a brightness of a preset area on the virtual model is smoothed based on the parameter of the virtual model after the adjustment.

As can be seen from formula (5), formula (7), formula (8), and formula (9), in response to changes of the parameter of the preset area, such as the width lineWidth, the moving speed speed, the color BandColor, or the like, the result of the first smoothing process and the result of the second smoothing process may change accordingly, that is, a smoothing effect of the brightness of the preset area may change dynamically with the audio information. Changes of the parameter of the preset area and the base color of the virtual model may refer to formula (1) to formula (4).

It can be understood that, in a case that the brightness of the preset area is smoothed based on the initial parameter of the preset area before S1301, the brightness of the preset area may be further smoothed, after S1303, based on the parameter of the preset area after the adjustment. In a case that the brightness of the preset area is not smoothed before S1301 based on initial parameter of the preset area, the brightness of the preset area may still be smoothed after S1303 based on the parameter of the preset area after the adjustment.

In another embodiment, the S1303 of displaying the virtual model in the target image based on the parameter of the virtual model specifically includes: smoothing the brightness of the preset area on the virtual model based on the parameter of the virtual model after the adjustment; and displaying the virtual model in the target image. For example, after adjusting the parameter of the virtual model based on the attribute of the audio information, the terminal may perform a smoothing process on the brightness of the preset area based on the parameter of the preset area after the adjustment. Further, the terminal displays the virtual model based on the parameter of the virtual model after the adjustment and the brightness of the preset area after the smoothing.

In an example, smoothing the brightness of the preset area on the virtual model based on the parameter of the virtual model after the adjustment includes: performing a third smoothing process on the brightness of the preset area on the virtual model based on an initial position of the preset area and a width of the preset area after the adjustment; and performing a fourth smoothing process on the brightness of the preset area on the virtual model based on a result after the third smoothing process and a preset smoothing parameter.

For example, after adjusting the parameter of the virtual model based on the attribute of the audio information, the terminal 21 may perform a smoothing process on the brightness of the preset area based on the parameter of the virtual model after the adjustment. The parameter of the virtual model after the adjustment may include: a base color albedoColor of the virtual model after the adjustment, a moving speed speed of the preset area after the adjustment, a width lineWidth of the adjusted preset area after the adjustment, and a color BandColor of the preset area after the adjustment.

For example, the terminal 21 may perform the third smoothing process on the brightness of the preset area based on the width lineWidth of the preset area after the adjustment and the initial position linePos of the preset area on the virtual model 23. A result after the third smoothing process may refer to formula (5).

Further, on the basis of the result of the third smoothing process, the fourth smoothing process is performed on the brightness of the preset area based on the preset smoothing parameter y and the color BandColor of the preset area after the adjustment. A result after the fourth smoothing process may refer to formula (7).

In an example, performing the third smoothing process on the brightness of the preset area on the virtual model based on the initial position of the preset area and the width of the preset area after the adjustment includes: performing the third smoothing process on the brightness of the preset area on the virtual model based on the initial position of the preset area, the width of the preset area after the adjustment, and the moving speed of the preset area after the adjustment.

For example, the preset area is movable, and the third smoothing process is performed on the brightness of the preset area based on the width lineWidth of the preset area after the adjustment, the moving speed speed of the preset area after the adjustment, and the initial position linePos of the preset area on the virtual model 23. A result after the third smoothing process may refer to formula (8). On the basis of the result of the third smoothing process, the fourth smoothing process is performed on the brightness of the preset area based on the preset smoothing parameter y and the color BandColor of the preset area after the adjustment. A result after the fourth smoothing process may refer to formula (9).

As shown in FIG. 4 , the terminal 21 generates five preset areas on the virtual model 23 and five preset areas on the virtual model 25.

Taking the virtual model 23 as an example, in a case that there is no audio information, in response to each of the five preset areas in the on the virtual model 23 being stationary, each of the preset areas may be displayed on the virtual model 23 in a static state with the initial position, the initial width, the initial color, and the brightness being smoothed in accordance with formula (5) and formula (7).

In a case that there is no audio information, in response to each of the five preset areas on the virtual model 23 being movable, each of the preset areas can move on the virtual model 23 at the initial moving speed of the preset area; meanwhile, the width, the color, the moving speed, and the brightness of the preset area smoothed by using formula (8) and formula (9) may remain unchanged when the preset area is moving.

In response to the terminal 21 acquiring the audio information and adjusting the parameter of the virtual model 23 based on the attribute of the audio information such that the parameter of the virtual model 23 changes with a change of the audio information, in a case that each of the five preset areas on the virtual model 23 is stationary, each of the preset areas can be displayed at its initial position with a variable width, a variable color, and a variable brightness smoothing effect.

In response to the terminal 21 acquiring the audio information and adjusting the parameter of the virtual model 23 based on the attribute of the audio information such that the parameter of the virtual model 23 changes with a change of the audio information, in a case that each of the five preset areas on the virtual model 23 is movable, each of the preset areas can move on the virtual model 23 with a variable moving speed. In a movement of the preset area, the width, color, and brightness smoothing effect may be variable.

For example, the color finally presented by the virtual model 23 is denoted as Color. The Color may depend on the base color of the virtual model 23 and the color of each of the five preset areas on the virtual model 23. For example, the color of a first preset area among the five preset areas is denoted as OutputBand[1], the color of a second preset area is denoted as OutputBand[2], . . . , and the color of a fifth preset area is denoted as OutputBand[5]. The color of each of the preset areas may be determined based on the result of the second smoothing process or the result of the fourth smoothing process. The Color may be expressed as formula (10):

Color=albedoColor+OutputBand[1]+OutputBand[2]+OutputBand[3]+OutputBand[4]+OutputBand[5]  (10)

As shown in FIG. 4 , the terminal 21 generates five preset areas on the virtual model 23 and five preset areas on the virtual model 25. Through the method described in the embodiments of the present disclosure, the position, width, color, moving speed, brightness transition effects, and other visual properties of the preset areas can change with a change of the audio information. In addition, the base colors of the virtual model 23 and the virtual model 25 may change with the change of the audio information. Therefore, the virtual model 23 and the virtual model 25 on the image of the human face can present a rendering effect of a neon light band that is linked with the audio information.

As shown in FIG. 4 , in a case that the neon light band rendering effect linked with the audio information is displayed on the image of the human face, in response to a shooting instruction from a user, the terminal 21 may capture an image of the human face with the rendering effect of the neon light band, or record a video of the human face with the rendering effect of the neon light band. Alternatively, the user may only preview the image or the video with the rendering effect of the neon light band on the screen. Further, the terminal 21 may transmit the image or the video of the human face with the rendering effect of the neon light band to other terminals or servers in response to a transmission instruction from the user.

In the method for processing a virtual model according to the embodiments of the present disclosure, after the adjustment on the parameter of the virtual model based on the attribute of the audio information, the brightness of the preset area may be further smoothed based on the parameter of the virtual model after the adjustment, so that the brightness smoothing effect from the centerline position of the preset area to the upper edge position and the lower edge position of the preset area may change with a change of the attribute of the audio information. Hence, the visual effect of the preset area is further enhanced.

On the basis of the above embodiments, some control buttons may be further provided on the user interface of the terminal 21. Reference is made to FIG. 14 . Multiple groups of arrows 141 are displayed on the user interface. Each group of arrows is used to set or adjust a single parameter of the virtual model.
